Description
The present invention relates to the method for the bracket (Tr ger) preparing home appliances, in the method, coating is coated with to the base material of bracket.In addition, the invention still further relates to a kind of stove plate (Kochfeldplatle) by the induction stove (Induktionskochfeld) prepared by method of the present invention and its favourable scheme.
The stove plate of stove is prepared by various material.Therefore known glass material related to this, as glass-ceramic.In this, with regard to regard to stove, need the material that must meet various condition.Also high crack security is needed, as withstand high temperatures is poor on the one hand at this.Especially it also needs to meet high weight demands to bear cooking apparatus as pan, tank etc.
Usually known structure only meets these requirements conditionally, in addition, and not only complexity but also expensive in preparation.
The object of the present invention is to provide the method for the bracket preparing home appliances, the method can realize simply and better meet the bracket concept of this kind of bracket requirement.In addition, the object of the present invention is to provide a kind of stove plate that better can meet the stove of above-mentioned requirements.
This object is that the method for feature by having claim 1 and the stove plate of the feature with claim 15 realize.
The method of the bracket for the preparation of home appliances of the present invention comprises the step base material of this bracket being coated with to coating.By an importance of the present invention, this base material is manufactured by casting process.When preparing this kind of bracket, in view of material structure and material composition, this processing sequence can have diversified change possibility.Can meet the demands with improvement thus, particularly the requirement of stove plate aspect.Especially, also cost effective method can be realized by this processing sequence in the preparation.Particularly compared with the processing sequence of compacting base material, obvious advantage can be had thus.
This base material is preferably by silicon-dioxide-powder and the preparation of gelatinous suspended substance of polycrystalline.This component mixture and can being particularly conducive to the state of solid of gel produced by it are continued processing, introduce other material and are prepared the bracket particularly having and adapt to personalized above-mentioned requirements thus.
Silicon-dioxide-the powder of this polycrystalline and the component of gelatinous suspended substance preferably mix mutually.Draft the mixture that specific processing sequence carrys out preparation and fabrication component especially for this reason, to make its pH value for 8-11, especially 8.5-10.
Advantageously regulation rotating speed is 700 U/min-900 U/min, and particularly the mixing tank of 800 U/min mixes these components.Preferably 25-35 minute is carried out, particularly 30 minutes with this mixing of the above-mentioned rotating speed of mixing tank.The method steps of this component mixing preferably at room temperature carries out.Especially reliably can realize fabulous abundant mixing thus and produce above-mentioned pH value.
Preferably preparing mean particle size is 7.5-8.5 μm, particularly silicon-dioxide-the powder of particle of 8 μm.
Preferably produce or prepare and there is 25-30 % by weight, the particularly gel suspended substance of 30 % by weight silicon-dioxide.
Specifically produce or prepare and there is 0.2-0.4 % by weight, the particularly gel suspended substance of 0.3 % by weight sodium oxide.
Preferably produce or prepare and there is 65-75 % by weight, the particularly gel suspended substance of 69.7 % by weight water.Here it is mentioned that, with its part by weight containing the composition of gel suspended substance of components silica, sodium oxide and water make its always 100%.
Preferably preparation is containing 55-65 % by weight, particularly 60 % by weight silicon-dioxide-powder and 35-45 % by weight, the particularly base material of 40 % by weight gel suspended substances.Here it is mentioned that, it is only mutually relative for should understanding this weight percentage between described component, not draws the base material of 100%.Therefore do not mean this base material to be only made up of these components.And this base material yet can have other material in its final component composition, particularly there is fortifying fibre.
Preferably, the filamentary material at least one being derived from crystalline silicon strengthens in the suspended substance padding and immerse and impregnated in and be mixed with silicon-dioxide-powder, and is sent in casting die by this pad.Preferably, being fed in gel-like material of this pad is carried out after immersing and flooding.
Preferably, there is the bracket of base material in the substrate containing two this enhancing pads through corresponding dipping.Preferably the fiber thickness of this enhancing pad is 2-4 μm, particularly 3 μm.
About preparation technology, preferably, the time length that enhancing pad immerses in this gelatinous mixture deriving from silicon-dioxide-powder and this suspended substance is 20-40 second, particularly 30 seconds.
Preferably, this casting die is the aluminium parts being coated with nickel, and these parts are correspondingly by the shape and size preparation of bracket to be prepared.Here, this casting die also comprises cover mold plate and side template except comprising end template.
About other program preparing bracket, in the end template of casting die, therefore introduce the medium of oil-containing, introduce a certain amount of gelatinous mixture containing silicon-dioxide-powder and suspended substance in addition.Can avoid when introducing the enhancing pad through dipping thus and produce bubble in the manufacture of this integral bracket thereafter and process of setting.
Then then two enhancing pads through dipping are mutually placed.For improving preparation technology further, the then rolling back and forth on the enhancing pad introduced with roller or like, makes the bubble can getting rid of other.
Then then apply the cover mold plate of casting die, and close this casting tool.This casting die has the hole then can being discharged unnecessary gel mixing material by it.This casting die through the longer time, particularly some hours, preferably removes the sidewall of this casting tool after closing after 10 hours.Then, then through for some time, also particularly some hours, cover mold plate or the cover mold wall of this casting tool preferably after 5 hours, is removed here.Then, then through for some time, preferably take out by casting tool the carrier structure produced as stove plate after 1 hour.
Then, in technique subsequently, the intermediate member of coating in rigidified substrate form.
Preferred coated is containing the material of glaze for this reason.
Particularly preparation has the liquid solution of Powdered glaze material for this reason.Here preferably the content of glaze is 35 % by weight.In addition, then also can introduce other fusing assistant-material (Flux-Material), its percentage composition is preferably 7 % by weight.All the other are preferably distilled water.In order to apply, preferably assembly is sent in the stove being preheating to and being preferably 100 DEG C.Be coated in and wherein carry out, if wherein solution is applied on base material, then preferred thus the moisture in coating to be steamed.
First this base material is coated with glaze in downside, is then coated with upside, is then then coated with lateral edges.In stove, keep certain residence time subsequently, this time is preferably some minutes, particularly 10 minutes, can evaporate remaining water at this moment.Then then the unit construction so prepared is sent into a few Baidu, preferably keeps some minutes, particularly 10 minutes in the stove of about 900 DEG C, thus containing glaze coating can with base material almost (quasi) fuse.
Preferably prepare a kind of bracket by the method, it is the stove plate of the home appliances for cooking food.
In addition, the invention still further relates to stove prepared by a kind of the inventive method or its advantageous scheme, particularly respond to the stove plate of stove.
According to schematic figures in detail embodiments of the invention will be described in detail below.
